Cicindelidae. 

 Cicindela, Linn. 



1. C. Senegalensis, Dej. I. 117. 



Capite thoraceque viridi-cupreis, subrugosis ; elytris viridi-aeneis ; 

 margine laterali, lunula humerali apicalique, fascia media 

 obliqua sinuata suturaque subsinuata abbreviata, albis. 



Long. 4^ lin., lat. 1£ lin. 



Only a few specimens have been received of this species. 

 They vary a little from the usual form of Senegalensis in having 

 the thorax comparatively a little narrower, and the ground- 

 colour of the elytra being less green, it being reddish- brassy 

 with green reflections ; but the markings are the same, and it 

 corresponds in other respects ; therefore I have no doubt it is 

 merely a variety of Senegalensis. 



2. C. vicina, Dej. 5. 244. 



Var. confusa, mihi. 



Snbcylindrica, supra cupreo-viridi aenea ; elytris margine laterali 

 subinterrupto, lunula humerali subinterrupta, altera apicis 

 dentata, strigaque media recurva subinterrupta incumbente, 

 albis ; femoribus subtus rufis. 



Long. 4-5 lin., lat. 1^-lf lin. 



The specimens I have from Old Calabar differ slightly from my 

 other specimens of vicina, Dej., but not sufficiently to constitute 

 a distinct species. The labrum is more prominent in the 

 Old Calabar specimens, but that part varies a good deal in form, 

 and particularly in the development of the three teeth in front. 

 In the males they sometimes appear almost entirely wanting. 

 The first joint of the antennae in vicina, Dej., is green. In the 

 Old Calabar species this joint is either wholly brown, or brown 

 below with a virescent tinge above. The white marks on the 

 elytra are broader in vicina than in this variety, and its apical 

 margin of white slopes somewhat parallel with the margin, 

 while in this variety its upper edge is nearly square or parallel 

 with the base; but the breadth, extent and form of the white 

 markings on the elytra vary a good deal in different individuals. 



I obtained a specimen identical with my Old Calabar examples 

 from M. Jekel, under the name of confusa, Gehin ; but I have 

 not been able to ascertain that it has been anywhere described
